What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Obesity is a significant global public health issue. The incidence of improper physical activity (PA) has increased in recent decades. A lack of self-efficacy and the necessity to perform PA associated with excess body weight may limit its potential benefits for obese individuals. Consequently, this study investigated the mediating role of self-efficacy in the relationship between obesity and PA in adult females. In this cross-sectional study, 149 adult females aged 20 to 50 years with a body mass index >25 were recruited. The participants in this study completed a self-administered questionnaire containing the official Arabic version of the long form of the International Physical Activity Questionnaire and the General Self-Efficacy Scale. The associations between the measured variables were tested using a multiple linear regression model. This study demonstrated that obesity negatively predicted PA (B = -0.954, P < .001) and self-efficacy (B = -2.63, P < .001). When both variables were considered, obesity remained a negative predictor of PA (B = -1.63, P < .05), while self-efficacy positively predicted it (B = 0.963, P < .01). Furthermore, there were statistically significant direct and indirect associations between obesity and PA through the role of self-efficacy (P ≤ .05). These results indicate that self-efficacy partially mediates the effect of obesity on PA among adult females. Self-efficacy had a mediating effect on the association between obesity and PA in female adults. These findings highlight the importance of self-efficacy as a potential target for clinicians and researchers aiming to increase PA in obese populations.
